Floral 3D pattern more efficent way
There are at least 2 ways, the Displace modifier or the Sculpt mode.
You could find a black and white floral repeatable pattern, blur it a bit:

Then create your object, subdivide it a bit, give it a Displace modifier with the floral pattern as texture (If you've unwrapped your object you can choose Coordinates &gt; UV), give it 2 Subdivision Surface modifiers, put them above and below the Displace modifier, and when you're glad, duplicate the object and apply the modifiers:

You could also sculpt on your object. In that case make sure your object is subdivided enough, then in Sculpt mode, use your pattern as texture image (go into the Properties panel &gt; Texture to load your pattern) and set the Mapping to Stencil (left click to move the image, left click + Ctrl to rotate the image, left click + Shift to enlarge). This way you can be more precise:


If you struggle in any of those steps, please tell me.
